2009 Infiniti M45

Base MSRP $52,150

Part sport sedan and part posh luxury car, the 2009 Infiniti M35 and M45 stand out from the market due to their available onboard technology features, including a sophisticated rear-wheel steering system and a lane-departure system that actually nudges the vehicle back into its lane. Both M models also stand out for having a quiet interior, a well-controlled ride, and strong, smooth powertrains.
